TherAir Plus Personal Energized Oxygen System
- Breathe light-treated air through a soft cannula, from L.A.E.O. technology
- Effortless sessions: press one button and breathe, timer runs up to an hour
- Quiet enough for sleep, meditation, or deep work
- Take it anywhere: under 2 lbs, worldwide plug set included
Filtered air, activated by light. Why that matters
Incoming air passes a replaceable filter, gets exposed to light inside the unit, and flows out through a soft nasal cannula. It runs for up to an hour at a time on the included plug-in timer, then rests for an hour before the next session. At 26.5 oz with a worldwide plug set, it is built to sit on a desk or nightstand as part of a breathing or relaxation routine.
TherAir Plus is used as part of a breathing and relaxation routine; it is not a medical device and does not treat, cure, or prevent any condition.

Description
The TherAir Plus is a personal energized oxygen system built around Therasage's Light Activated Energized Oxygen (L.A.E.O.) technology, a light-based process that treats filtered air before delivering it through a soft nasal cannula. Many people breathe with it at the desk to support focus through the day, or at the bedside as part of a wind-down routine.
Use it in the moments that matter most: an hour at the desk before deep work, or a quiet session before bed. It arrives ready to go with the cannula, timer, adapter, and spare filters. TherAir Plus is a wellness device, not medical oxygen, so check with your practitioner if you have a respiratory condition.
Key details
TherAir Plus Personal Energized Oxygen System is a travel-size energized oxygen system for a single user, with one output port. It uses Therasage's Light Activated Energized Oxygen (L.A.E.O.) technology and delivers air through a soft nasal cannula. Sessions run up to 1 hour followed by a 1 hour rest on the included plug-in timer. The unit measures 6.7 × 3 × 1.6 in, weighs 26.5 oz, and runs on 100 to 240V with a worldwide plug set. The box holds the TherAir Plus, cannula, 3 spare filters, timer, AC adapter with 4 plugs, and guide.
It fits routines built around energy, focus, and recovery.
Is this right for you?
You'll get the most from it if
- Your nightstand or desk is already crowded; it takes up about as much room as a paperback.
- One session at a time suits you; it wants an hour of rest after each hour of use, so no marathon days.
- You stay settled while it runs; the cannula keeps you within a few feet of the unit.
- Upkeep stays light; a monthly filter rinse and a twice-yearly swap are the whole maintenance list.
Maybe look elsewhere if
- Two people want sessions at once, or you need continuous back-to-back use; the TherAir Pro handles both.

Why it earns a place in the stack. Most routines work on light, heat, and sleep, and skip the air itself. TherAir Plus adds a quiet air layer: a light-based process treats the air you breathe through a soft cannula, at the desk or bedside. It cleared the same bar as everything at Kove, with support we stand behind after the sale.

Our approach
Every product earns its place.
No single thing changes your biology on its own. What matters is the system, and whether each piece earns its place. Here is how a device makes it into Kove.
01
Start with the evidence
Where there is research behind how something works, we read it. We look at the real mechanism a device relies on, like the wavelength, the frequency, or the dose, and whether the evidence holds up. Substance comes before marketing, and we are honest about how strong that evidence is.
02
Separate mechanism from marketing
A claim is not a mechanism. We check a device's real output against its stated one: does the panel emit the 660 and 850nm it advertises, at the irradiance that makes those numbers matter? The marketing language gets set aside. The measurable spec is what we judge.
03
Verify build and dose
Even a good idea does nothing if the hardware is weak. We confirm the output is consistent, the dose is usable in a real daily routine, and the build holds up over years, because a device only helps if it lasts as long as the habit.
04
Held to one standard
What clears every step earns its place in the system, held to the same standard as everything else. That consistency is what you can count on.
